In its mission to support the 20th Tactical Fighter Wing, the
320th Munitions Maintenance Squadron existed from 1964 to 1972
- a surprisingly
short 8 years. From its creation in 1964 through 1970, the 320th
was located at RAF Wethersfield. For the remaining time, the squadron was at RAF Upper Heyford. The 20th TFW was part of the 3rd Air Force, which was part of USAFE.
